U.S. Environmental Protection Agency Administrator Gina McCarthy says data is being collected on the levels of lead in Flint’s water system.

She told reporters Tuesday after touring a food bank in the city that the agency expects to be able to share its findings in April. McCarthy said that “hopefully, by next month” the EPA will “be able to give people news.”

Flint was under state financial control in 2014 when officials switched its water service from Detroit’s system to the Flint River. But state officials did not require Flint to add anti-corrosive chemicals when the city began drawing water from the river.

The water caused lead to leach from aging pipes and water lines into some homes. Tests have shown high lead levels in some Flint children.

Flint, north of Detroit, was under state financial control in 2014 when it switched from Detroit’s water system to the Flint River to save money. Corrosive water from the river leached lead from old water lines into some home.

Tests have shown high lead levels in some Flint children.
